Abstract : Pulsars are rotating neutron stars(NSs) that produce a beam of radio waves along their magnetic axis. They are known to have very stable periods; nevertheless, they show sudden jump in their rotation rates which is known as pulsar glitch. Glitches are the direct manifestations of the internal structure of NS. The superfluid neutrons inside the NS are believed to be the cause of such phenomena. Pulsar glitches are generally followed by exponential recoveries. In order to understand the coupling between several components of the NS interior we need to investigate this recovery phase after a glitch. We have been trying to monitor some of the high glitch rate pulsars using the upgraded Giant Metrewave Radio Telescope (uGMRT) and Ooty Radio Telescope (ORT). Here, we present some of the glitches detected as a result of such monitoring program and how can we probe the internal structure of the NS with the help of such observations.
